- said stopper has a recess in each domed part, to facilitate the elastic deformation of said convex parts.
- said plug comprises an external sealing part, formed on its external periphery.
- said outer sealing part comprises at least one peripheral bead sealing against an inner side wall of said reservoir.
- a subject of the present invention is also a method for filling a fluid dispenser device comprising a body, a reservoir containing one or two doses of a fluid product, said reservoir comprising a plug which closes said reservoir in a sealed manner before actuation, a dispensing head provided with a dispensing orifice, and dispensing means for dispensing at least part of said fluid product through said dispensing orifice during actuation, said plug being symmetrical and reversible, said stopper comprising an elastically deformable internal part which, when pressure is applied to an axial side of the stopper, deforms to open a passage, and which, when said pressure ceases, resiliently returns to its rest position in which it closes said passage, said method comprising the following steps:
- the filling continues at the start of the withdrawal of said filling tube.
- Figure 1 is a schematic cross-sectional view of a nasal fluid dispenser device according to an advantageous embodiment
- FIG. 2 is a detailed schematic view of part of the device of FIG. 1, before actuation,
- Figure 3 is a view similar to that of Figure 2, during actuation,
- FIGS 4 to 7 are schematic views showing the phases of filling the tank of Figures 1 to 3, and
- FIG. 8 is a schematic cross-sectional view of a stopper according to an advantageous variant embodiment.
- proximal and distal refer to the delivery port.
- axial and radial refer to the longitudinal central axis of the device.
- upper, lower, “top” and “bottom” refer to the upright position of the device shown in Figures 1 to 7.
- FIG. 1 there is shown an example of a nasal fluid dispenser device to which the present invention applies.
- a nasal fluid dispenser device to which the present invention applies.
- it is a single-dose device, in which the entire dose of fluid is dispensed in a single actuation.
- the present invention could also be adapted to other types of devices, such as for example devices of the bidose type, containing two doses of fluid to be dispensed in two successive actuations of the device.
- the device comprises a body 1, comprising a radial flange 5 to support the user's fingers during actuation.
- This dispensing orifice 21 serves to dispense a dose of fluid product out of said dispensing head 20 when the device is actuated by a user, this dispensing being carried out by dispensing means.
- the nasal dispensing head 20 is made in one piece with said body 1. It should be noted that the present invention could also be applied to a device comprising a buccal dispensing head. More generally, the present invention applies to all types of single-dose or two-dose devices.
- the body 1 receives a reservoir 10.
- the reservoir 10 can be formed by a hollow and blind body 11, comprising a single opening closed by a stopper 12 and containing a single dose of fluid to be dispensed. single actuation of the device.
- the stopper 12 is made of a deformable material, such as an elastomer.
- the distribution head 20 comprises passage means 13 which connect, during actuation, the reservoir 10 to the distribution orifice 21.
- These passage means advantageously comprise a hollow rod, preferably integral with the body 1, but which could also be produced separately and assembled in said body 1.
- This hollow rod 13 opens on its proximal side into the dispensing orifice 21, and cooperates on its distal side with the stopper 12 to move it relative to the reservoir 10 during actuation.
- the stopper 12 has an outer sealing part 125, formed on its outer periphery.
- this sealing part 125 comprises three peripheral beads, an upper bead, a central bead and a lower bead, which seal against the internal side wall of the reservoir 10.
- any number beads could be provided, for example a single bead.
- the stopper 12 comprises an elastically deformable internal part 124 which, when pressure is applied to an axial side of the stopper 12, deforms to open a passage 15, as can be seen in FIGS. 3, 5, 6. and 8.
- the internal part returns elastically to its rest position in which it closes said passage 15.
- said internal part 124 may comprise two radially opposed domed parts 1241, 1242 urged at rest radially against one another to seal said passage 15. The application of an axial pressure radially deforms these two convex parts. away from each other, to open the passage. When the pressure ceases, the two curved parts resiliently return to their resting position, which is closed.
- the stopper 12 comprises a recess 126 in each domed part 1241, 1242, to facilitate the elastic deformation of the bulging parts.
- a stopper can in particular be produced by additive printing.
- the stopper 12 is perfectly symmetrical and therefore can be used either way in one direction or the other.
- This reversible nature of the stopper 12 is advantageous, in particular during assembly. Indeed, it is not necessary to orient the stopper 12 in a particular direction, so that the assembly of the stopper is simplified and therefore less expensive.
- the reservoir 10 is moved axially upwards relative to the body 1.
- the stopper 12 opens under the pressure of the fluid product which is incompressible, to open said passage 15, then the stopper 12 slides in the reservoir 10 to expel the product through said hollow rod 13. In this mode. embodiment, it is the stopper 12 which forms the distribution means.
- the reservoir could not be formed by a blind hollow body having only one opening, but by a hollow cylinder open axially on both sides.
- This cylinder would then be closed on the proximal side by a first plug according to the invention and on the distal side by a second standard plug, the volume defined between said two plugs containing the fluid product to be dispensed.
- the user actuates the device, as described above, he will press axially on the actuating body to make it slide axially towards the dispensing orifice. This causes the second plug to move inside the tank.
- this movement of the second stopper will therefore open the first stopper and the contents of the reservoir will be distributed through said first stopper and said hollow rod by the second stopper, which then acts as a piston.
- the second stopper which then acts as a piston.
- it is the second plug which forms the distribution means.
- the invention could also be applied to a device of the bidose type.
- the contents of the tank would be distributed in two successive actuations.
- Document WO2014147329 describes an example of a bidose device.
- FIGS 4 to 7 show the successive steps of an advantageous filling process.
- the plug 12 is first inserted into the bottom of the reservoir 10, as shown in Figure 4.
- a filling tube 30 is then inserted between the two domed parts 1241, 1242, as visible in FIG. 5, and the reservoir 10 is filled with said fluid product, as illustrated in FIG. 6. Under the effect of the hydraulic pressure fluid, the plug 12 rises in the reservoir 10.
- the volume of the reservoir arranged behind the stopper 12 can therefore be filled almost completely, with the exception of the small volume occupied by the end of the filling tube 30.
- the filling continues at the start of the withdrawal of the filling tube, until 'so that the tube reaches the point of contact of the two convex parts, which makes it possible to eliminate the small dead volume linked to the tube.
- this closing of the passage 15 drives out any residual air liable to remain at this location.
- the present invention provides several advantages, including:
